Btw, you're likely to get a prompter response if you CC me directly on patches you want merged.

David, I guess the problem is likely that get_maintainers.pl does not list you for ppc related stuff except the spapr files. How long is Alex still going to be away? Maybe you should get listed in some more ppc-related entries as co-maintainer in the MAINTAINERS file, for the time being? Thomas

With this, it's easier to know if a guest uses an invalid and/or unimplemented DMA channel. Signed-off-by: Hervé Poussineau <hpoussin@reactos.org> --- hw/misc/macio/mac_dbdma.c | 25 +++++++++++++++++++++++-- 1 file changed, 23 insertions(+), 2 deletions(-)
